Unable to turn on Windows Defender in Security Center

I'm having some issues with the Malware Protection in the Security Center.

First, any of the anti-virus programs I've installed are detected by the SC.
Neither the EZ anti-virus nor the AVAST are detected. Both states that are
Windows Vista Beta 2 Ready. But they don't work for me.

And finally, I can't turn on Windows Defender in the Security Center. When I
try to activate it, he searches for any available update. Once he detects he
is up to date, a warning message window pops-up and there's no way to turn it
on.

Because of these two issues, I'm continuosly getting alerts from the
Security Center. And I know that both programs are up and running.

Any idea? Thanks in advance

I have the same issue. When Vista was initially loaded, both the AVAST and
Windows Defender were detected and worked normally in Security Center.
About two days later, after a reboot, I got same issue as you with the
Security Center. I reported the problem to MS (Feedback, MS Beta Client)
and I would ask that you do the same as it may help them troubleshoot the
problem.
